“The basic combat rifle for home property defense in my opinion is anything that throws lead with reasonable accuracy at 100 yards or better, doesn’t jam and requires little to no maintenance.”
A Mossberg 12 gauge pump with slugs would work, too. Use 00 buck for close encounters.
Double-barreled 12 gauge loaded with 00 Buckshot always ready. Indisputably, nothing better for just plain killing someone who should not have broken in to the house. After that guys falls dead or lays there screaming, a couple of loaded handguns can be accessed for whomever has the nerve to keep trying. For normal civilian use, don't need that fancy SKS or AR firepower.
